Abstract (en)
[origin: EP1361503A2] A key input device in which an input key(12,30,42,50) is oscillated with respect to an opposing surface (22, 59) facing a bottom portion(14a,32a,46a,51a) thereof and in which depression of the opposing surface(22,59) with the input key(12,30,42,50) at a normal operating point(16aˆ¼16d) situated above a contact portion (22aˆ¼22d, 59aˆ¼59d, 60aˆ¼60d) of a board (22, 58) causes the input key(12,30,42,50) to tilt in a normal oscillating direction(21aˆ¼21d) to effect input at the contact portion(22aˆ¼22d,59aˆ¼59d,60aˆ¼60d). Either the bottom portion(14a,32a,46a,51a) of the input key(12,30,42,50) or the opposing surface(22,59) is equipped with guide protrusions(20aˆ¼20d,25aˆ¼25d,34aˆ¼34d,47aˆ¼47d,54aˆ¼54d, 63aˆ¼63d) arranged symmetrically with respect to an imaginary line(21aˆ¼21d) extending along the normal oscillating direction(21aˆ¼21d) of the input key(12,30,42,50). Depression of the opposing surface(22,59) with the input key(12,30,42,50) at an erroneous operating point deviated from the normal operating point(16aˆ¼16d) results in the guide protrusions(20aˆ¼20d,25aˆ¼25d,34aˆ¼34d,47aˆ¼47d,54aˆ¼54d,63aˆ¼63d) guiding the input key(12,30,42,50) to tilt in the normal oscillating direction(21aˆ¼21d) while abutting either the bottom portion(14a,32a,46a,51a) of the input key(12,30,42,50) or the opposing surface(22,59).
